DERRICK.

SBEGIFIOATION forming part of Letters Patent No. 514,355, dated February6, 1894.

Application filed May 26, 1893. Serial No. 475,580. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL R. FRENCH, a citizen of the United States,residing at Farmington, in the county of Van Buren and State of Iowa,have invented a new and useful Derrick, of which the following is aspecification.

My invention relates to improvements in derricks, the objects in viewbeing to provide a derrick that is portable, exceedingly strong anddurable; that consists of few parts and is adapted especially forelevating and carrying deposits of hay from the ground to and fromstacks, whereby the hay may be conveniently ricked or stacked; and,furthermore, that is capable of being operated by horse power and whichrequires but one attendant during such operation; and finally to providemeans for shipping and unshipping the boom.

With these and other objects in view the invention consists in certainfeatures of construction hereinafter specified and particularly pointedout in the claims.

Referring to the drawings:-Figure 1 is a perspective view of a derrickconstructed in accordance with my invention, the parts being in theposition they occupy when in the act of taking up a deposit of hay. Fig.2 is a similar view, the parts being in the position they occupy when inthe act of delivering a deposit of hay. Fig. 3 is a longitudinalsectional view of a portion of the track and the sliding dog arrangedthereon. Fig. dis a vertical longitudinal sectional View through theupper end of the mast and the central part of the lever. Fig. 5 is adetail of the bearing-collar and socket combined.

Like numerals of reference indicate like parts in all the figures of thedrawings.

The truck upon which I mount the derrick consists in this instance of aseries of three runners 1, and the same have let into their upper edgestransverse beams 2. These beams project beyond one of the runners andhave their edges terminating upon a circle concentric with that point ofthe truck where the central beam and central runner intersect.Surmounting the outer ends of the beams and the rear ends of the runnersis a curved track or way 3, the same being formed of I-iron and havingits lower flange or base securely bolted to position to the said beamsand runners. A central bearing mortise l is located at the intersectionof the central-beam and centralrunnerand stepped therein atits lower endis a rotatable post or mast 5. Between its ends the post or mast has anannular reduction or bearing-portion 6, and surrounding the same at thispoint is a pair of opposite half circular collar-sections 7, which haveflanges 8 at their ends, that are bolted together as at 9, and whichfurthermore are provided with sockets 10. Into these sockets take andare secured the upper ends of a series of braces l1,whose lower endsrest upon the front and rear beams 2 and are connected to the same attheir points of intersection with the outer runners 1 by angle-plates 12bolted to the beams-and to the braces.

The upper end of the post or mast is bifurcated or slotted as at 13, andone of the bifurcations or terminals is longer than the other and hassupported thereon in any suitable manner a pulley 14. A hoisting-rope(shown by dotted lines in Fig. 2) may be passed over the pulley and downthrough a guide-pulley 16 conveniently placed upon the frame, and to itmaybe hitched a horse for the purpose of operating said hoisting-rope.The upper end of the rope has a book 17, for the purpose of engaging thehereinafter described boom for the purpose of lifting the same to itsbearing in the mast. The boom 18 preferably consists of a number oftimbers bolted together at suitable points so as to render it solid andis of such width as to fit between the aforesaid bifurcations, eachtimber being of such length as to permit of its insertion in afreight-car. Perforations are formed in the bifurcations and in the boomand through the same passes a transverse bearing-pin or shaft 19, whoseends project beyond the opposite bifurcations and have fitted thereoverloose sleeves 20, whose outer ends project beyond the shaft and arenotched as at 21. Interposed between the inner ends of the sleeves andthe mast is a pair of loose washers 22, against which the inner ends ofthe sleeves bear. The boom, as is usual, is tapered from its butt towardits operating end, and a metal collar 23 is driven thereover. This metalcollar has upper and opposite side eyes 24: and 25 respectively, andthey are longitudinally oppositecorresponding eyes 26 and 27, formedrespectively upon the upper and opposite sides of the boom near itsbutt. Between the side eyes perforated brackets 28 are located andsecured to the sides of the boom, and truss-rods 29 are connected to thesaid side eyes, pass" through the brackets,and rest in the notches inthe outer.

rendered rigid and strong, being thoroughly braced as shown. The boom isfurther provided at its rear end with a pulley 33 and has its lowercorner cut away or beveled as indioatedat 34. g

Mounted for movement upon the circular track before described is asliding plate or carriage 36, from the opposite edges of which dependL-shaped keepers 37 that engage with the flange of the track and serveto retain the carriage imposition thereon; A pair of bearing-ears 38 isformed upon the upper side of the carriageand the upper ends thereof areconnected by a bail 39, to which is attached one end of theoperating-rope 40, the remaining end being passed up over the pulleyupon the butt end of the boom anddown under a guide-pulley 41 locatedupon the carriage, and from thence through a system of guidepulleys 42to one end of the track, where af-- ter passing around a pulley 43terminates in suitable draft devices '44, through which draft may beapplied in the usual manner. A stop 45 is located upon the operatingrope, so that after saidrope has been drawn a certain distance the stopcoming in contact with the housing of the pulley upon the rear end oftheboom will cause said boom to become depressed or lowered at said endand a consequent hoisting at its opposite or outer end.

Loosely pivoted between the bearing-ears of the carriage is an L-shapeddog or looking-latch 46, whose outer end is heaviest, carries a loosefriction wheel, and is adapted to fall by gravity and engage at said endwith the end of the track and thus lock the carriage against movementupon the track until after said locking-end has been elevated by adepression of the opposite end of the dog, through the medium of thebutt end of the boom, which is drawn down and contacts therewith and isridden over by the beveled portion thereof.

It will be understood that the outer end of the boom is provided withthe usual hay-sling and fork, not shown herein, whereby deposits of haymay be grasped.

In operation, the parts being in the position shown in Fig. 1, theoperating-rope 40 is loosened so as to permit the outer end of the boomto lower and a deposit of hay is engaged by the fork or sling, whereuponthe team is started and the operating-rope drawn through the system ofpulleys until the butt of the boom is drawn down so as to bear upon thetail-end of the dog or latch, which causes an elevation of the oppositeend of said dog and a consequent unlocking'of the carriage from thetrack and the tail end of the dog to bind upon or clamp the rope. Acontinued draw lng upon the rope causes the carriage to move over thetrack toward the system of guide-pulleys, the rope being securely held,

and thus swing the boom with its deposit of hay over the proposedhay-rick, where the hay is dropped. After the hay has been liberated,the carriage is moved back to the starting point, where'it islocked bythe dog, and the rope 40 released and its front end relowered for anewdeposit of hay, such return of the parts being accomplished by adrawing upon the fork or sling supporting rope.- By the continuedoperation of the derrick it will be seen that deposits of hay may besuccess ively engaged and raised and swung to a point I over the rick,whereby an operator standing upon the rick may readily distribute thesame,

thus forming a rick that is uniform.

Various changes may be made in the de tails of my inventionwithoutdeparting from the spirit thereof, and I therefore do not limitthe same to such details as I have herein shown and described.

When moving theapparatus one end of the rope 40 may be tied to theopposite side of the machine frame and the team hitched to the middle.After arriving at its destination, the machine is of course staked down.The derrick will be found useful in handling freight, rock, 850.
